IMPROVEMENT IN WlNDOW-SASHES.

Specification forming part of Letters Patent No. 138,921, dated May 13,1873; application filed April 12, 1873.

To all whom it may concern:

Be it known that I, DAVID W. Noxns, of Bennington, in the county of.Bennington and State of Vermont, have invented a new and valuableImprovement in Ventilating, Dust-Excluding House and Car Window; and Ido hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawing making a part of this specification,and to the letters and figures of reference marked thereon.

The Figures 1, 2, and 4 show modifications of my invention. The Figs. 3,5, and 6 are details of the same.

My invention has relation to windows constructed with'a view to theexclusion of dust and the ventilation of apartments; and consists in thenovel construction and arrangement of the parts hereinafter describedand claimed, which are designed to be effective for the purposes named.

A of the drawing represents the frame of a window, and B a windowproper, hinged and operated therein, as hereinafter described. Isometimes form my windows of a series of frames, A, and windows B, sothat the former may represent the stiles and the latter a single pane ofthe sash., In this window B I arrange a glass, as shown at 0, around therim of which I affix a strip of rubber for packing, as shown at a onFig. 2. This glass sits in a groove or channel inside the frame A, andis held in position bythe rubber strip last mentioned and the hingeddoor next described. D represents a swinging door adapted to lit insidethe frame, as shown on Fig. 4. One pintle of its hinges is shorter thanthe other for convenience of adjustment or removal. It

' is attached to the frame by means of its pintles and arms, as shown atc, which pintles fit in the eyes of the screw-heads f. They are securedin place by means of the flanged head of the screw f, in the mannershown on Fig. 6. These doors D serve as a substitute for putty to holdthe glass or other lighttransmitting material in its proper positioninside the frame. The screws f and f are arranged in suitable nutsattached to the frame, and serve to hold the door D in the positiondesired and to press it down upon the glass at will. In place of theglass O I substitute a frame of wire-cloth, as shown at d incross-section, to serve as a fly or mosquito net. I also substitute forsaid glass a double or folded wire frame, as shown at h on Fig. 5, andpartially illustrated on Fig. 1, between which folds or'frames I placecotton batting or wool of any color desired. This arrangement serves notonly to exclude dust, but also to give such a hue of color to theapartment as is deemed most desirable. A hue of green or black isconsidered preferable, but white is found most convenient when light forreading is required. The letter H represents a frame having openings inits sides, and. is fully described in my patent of March 11, 1873. Thisframe is designed to be used interchangeably with the windows, glass,&c., and the door D hereinbefore described. I lay no claim to theinvention thereof in this application.

A mirror or glass pane may be inserted in this last-mentioned frame, atwill, for the convenience of the inmates of the apartment.

My device is applicable to dwellings, churches, and structures generallyfrom which it is desirable to exclude dust and promote ventilation, andit is peculiarly well adapted to railway cars.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the frame A, door D, and screws f f with theinterchangeable glass 0 and wire frames d and h, substantially asspecified.

2. The screw f, having flanged head, as described, in combination withthe frame A and door D, constructed and arranged substantially as andfor the purpose described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
